接続端子に接続するといった煩られしい作業が必要で、
部品点数も多く、多大な組付は時間を要するという問題
点があった。Since the connector part for connecting to the drive power source is located at a distance from the motor housing 4, it is not preferable to extend the end of the winding of the coil 20 (about 0.211 diameter) to the connector part due to the risk of wire breakage. . Therefore, in the stator cores 1a, 2a, the ends of the windings are connected to the slightly larger diameter lead wires 22 by soldering, etc., and after covering the connection parts with short and small insulating pipes etc. for insulation. , Fold the covered part and wrap it with insulating tape toward the center to secure it. Further, the lead wire is passed through the through hole 26, covered with a relatively long insulated pipe, and extended to the connector portion. Furthermore, it requires the cumbersome work of inserting a waterproof plug into the tip of each lead wire and connecting it to the corresponding connection terminal.
There were problems in that the number of parts was large and the extensive assembly required time.
